Then get a pre filter and a HEPA to attach to it. Otherwise do what everyone else does without spending an assload of money and practice.

It would create a lot of turbulence. It would not be be bad for your mushies, but would be bad for sterile work.
It would not pull spores from outside if you use a hepa.
What you're talking about doing will be expensive and unnecessary.
You seem like a good guy so I don't want to offend you, but I have to be honest....you are thinking in the wrong direction.
Before you did all that, buy a prebuilt flowhood. You could save some money and build one, but there is no shame in buying one already made.
I prebuilt flowhood will be much cheaper than a positive pressure sterile room.
I only suggest this because you seem to have little faith in your SAB. But I honestly thing it is your techniques and methods. I'm not trying to dis you, I'm trying to be honest.

No offense taken. I would really love to build a flow hood, I just have no money, but I do happen to already have an ionizer which is why I was asking. I also have an air purifier with a built in carbon filter, hepa filter, and I'm pretty sure it also has an ionizer on it. That's why I was asking, just because it's here, I'm wondering whether it would improve things to use it or not.
So far I've really not noticed much of a difference between working in the SAB or the open room, so I guess on some level I don't have much faith in the SAB. I used to never use one, though this was in a different house, and actually have been more successful there (growing indoors) than here with the SAB. I understand the concept behind the SAB, but it just seems kind of arbitrary tbh. It's not as if the air in a SAB is ever actually 'still,' the idea is just that it's moving less than the air outside of the SAB. So say I take my grow room and stuff a towel under the door to limit the airflow, I feel it would essentially be just as 'still', if not more so, than the SAB itself, at least given a relatively clean (and/or sanitized work area).
Your hands are pretty huge in any SAB's I've seen relative to your body within most rooms I've seen, so... I dunno.. you get what I'm saying? Unless you move extremely slowly in a SAB the air won't be still, and the slower you move the more chance there is for contamination, it's a catch 22. If you're already shutting off any sources of airflow in your grow room when doing mycology work it just seems like you're putting a SAB in your SAB (the first SAB being your grow room). I also simply have bad eyes (or glasses : /) so it's simply hard for me to see when working in the SAB. Last night for instance I was drawing up some spores from a jar of sterile water (which actually germinated and I guess turned into a LC) and through the SAB I couldn't even tell if I had sucked anything up. Upon taking it out I saw nothing in there. There could of course have been spores in there I didn't see, but this solution was a month or so old and the spores and germinated mycilia had begun to form clusters, thus I assumed there wasn't.
I definitely need to work on my procedure I agree, so far I've noticed my moisture content is the most obvious flaw which often leads to trich, but for the time being outdoors is working really well for me at least. I'd really like to get this down so I can grow successfully over the winter though which is why I'm prepping in advance. Either way my room looks pretty awesome now haha, cleaned and rearranged everything, it's like brand new .
